GB/T 1592.2-2016Agricultural tractors -- Rear-mounted power take-off types 1, 2, 3 and 4 -- Part 2: Narrow-track tractors, dimensions for master shield and clearance zone (English PDF)

Foreword

GB/T 1592 "Agricultural tractors - Rear-mounted power take-off types 1, 2, 3

and 4" consists of the following three parts:

- Part 1: General specifications, safety requirements, dimensions for master

shield and clearance zone;

- Part 2: Narrow-track tractors, dimensions for master shield and clearance

zone;

- Part 3: Main PTO dimensions and spline dimensions, location of PTO.

This Part is Part 2 of GB/T 1592.

This Part was drafted in accordance with the rules given in GB/T 1.1-2009.

This Part replaces GB/T 1592.2-2008 "Agricultural tractors - Rear- mounted

power take-off types 1, 2 and 3 - Part 2: Narrow-track tractors dimensions for

master shield and clearance zone".

Compared with GB/T 1592.2-2008, in addition to editorial modifications, the

main technical differences in this Part are as follows:

- modified the standard name;

- changed "wheel track" to "minimum track" (see Clause 1 of this Edition,

Clause 1 of Edition 2008);

- added "wheeled tractors powered by single-cylinder diesel engine" (see

Clause 1 and 3.3 of this Edition);

- modified power range of type A tractor PTO (see 3.2 of this Edition, 3.2 of

Edition 2008);

- modified the requirements for rotation direction of tractor PTO (see 4.2 of

this Edition, 4.2 of Edition 2008);

- added the method of determination for standard rotary speed of PTO (see

1 Scope

This Part of GB/T 1592 specifies the dimensions for master shield and

clearance zone for rear-mounted power take-off types 1, 2 of wheeled tractors
